Allow only specified characters in tag names

[blebeka]

Is there a possibility to allow only specified characters in tag names?

I would like to have only [0-9a-zA-Z_]+ tags, that's it.

Can it be done? If not, are there any plans to implement such feature?

I want this too! Any solution?

it would be cool if these tags had a way to implement validation in general. Like only emails ?

I think that normally you should be able to do this by defining a custom tag and defining the name field with validators on it. At the very least this is a good FAQ thing
